tidySEM

The package tidySEM provides a ‘tidy’ workflow for conducting, reporting, and plotting structural equation modeling analyses. It does not perform model estimation, but instead allows users to estimate models in a software-agnostic way, using either the free open source R packages lavaan or OpenMx, or the commercial closed-source program Mplus (controlled through the R package MplusAutomation). The aim of tidySEM is to provide three specific functions:

1. Generate model syntax in a top-down, tidy way,
   • With particular attention to specifying mixture models in OpenMx
2. Tabulate model output in a publication-ready, uniform manner,
3. Make easily customizable graphs for SEM-models.

These functions are designed with the tidy tools manifesto (Wickham, last updated 23-11-2019) in mind, and interface with the existing suite of packages in the tidyverse.

Installation

You can install the public release of tidySEM from CRAN with:

install.packages("tidySEM")

If you want access to the latest developer version, including features that may not yet be finalized, you can install the development version of tidySEM from R-universe with:

install.packages('tidySEM',
                 repos = c('https://cjvanlissa.r-universe.dev',
                           'https://cloud.r-project.org'))

And if you are a developer and want to contribute to tidySEM, or want to install a specific historical version of the package, you can install directly from GitHub with:

install.packages("remotes")
remotes::install_github('cjvanlissa/tidySEM')

Documentation

Every user-facing function in the package is documented, and the documentation can be accessed by running ?function_name in the R console, e.g., ?graph_sem.

Furthermore, there are three main vignettes, describing the three main tracks of tidySEM functions:

1. A vignette about generating syntax and estimating models
2. A vignette about tabulating results
3. A vignette about making graphs
   • An additional vignette describes the graphing conventions for structural equation models.
